This invention relates to correspondence folders or files and has particular reference to i a correspondence folder having an. expansible pocket and anexpansible hinge cover. The principal object ofv the inventionis to provide a correspondence folder having an expansible pocket, forjretainer that holds the correspondence sheets snugly at all times and prevents them from falling out of the folder,- and at the same time holds them so that the papers in the file may be riffied and referred:

to so that any individual paper in the file may body 1 of the file has a flexible foldable hinge 2 unitingthe cover 3 to the body portion 1. On the bottom inner side of the body portion 1 is an expansible pocket at united to the base 1 by the corrugated expansible members 1 The cover, 3 maybealso connected tothe expansible pocket 4 by the hinge. member 6 ccmented to or otherwise connectedgto the cover 3, o-rif desired the pocket member A need not I be 'con-ncctedito the cover 8l'as indicated in cross:sectioninFig. 3,; a

Another object ofthe invention is to provide In operation the correspondence 'membe rs orzsheets 7 are placed ntheexpansible pocket wtwhich extends up about one-quarter'ofthe distance from the bottomtothe top of the an expansible hinged cover that will be held in alignment with the body of the file for all thicknesses of the file, Whether empty or full or at points in between.

Another object of the invention is to provide a ready reference desk file in which the papers may be kept in order and referred to without removal from the file. V Other objects and advantages of the invenbase member, 15 As the sheets 7 accumulate tin thepocket4the pocket tispushed ofutor expanded on the expansible or fluted members 5; s-lWhere the hingefiunitesthe pocket 4.

Referring to the drawings wherein similar reference characters are used to denote eorp I hinge 6 is. used to attach the 'pocket t; to the respondingparts throughout, the base or stood that many modifications or changes in 1 the-arrangements of parts and details of construction 'may be made without departing from the spiritbof the invention as set forth! I, therefore,

showing the inside of the folder and the core "with the base member 1 but allows the ex ,pansion of the pocket 4. Where a relatively still hinge 2 .isused toconnect the base mem-v berl with. the coverS'rtmaynot be necessary to use the.hinge fixbecauseifthe hinge 2 is stiff-enough the cover 3 will be held in alignment', but-it has. been (found that'with the ,usual hinges employed in folders of this kind thecover 3 is aptto sago-ut of line with the base lwhich makes an; awkward a 1rd untidy file,particularlyWhere it is used for desk or correspondence use where a pleasing looking and substantialy file is desired.

It will be seen from Fig. 1 that to refer to the sheets 7 in the pocket lit-1s not necessary torcmove them from the pocket 4. .The hand may be placed on the pocketet to tighten the *sheets in the pocket and then the tops of the sheets? lifted and pulled up so that the various sheets may be referredto like the pages on line 22 of Fig. 1, wherein the cover is;

of a book, 1 and thefdesired sheet found and consulted; If desired this sheetn'ia-y be taken from [the file Without: removing any of the othersheetsor: it in-ayloe. referred to in the fileiwithout removing it. V

Another-desirable: featureexists where the.

-placed therein. iThis hinging of the pocket 4 cover 3, namely, that when the cover 3 is thrown open and extended outwardly towards a position of 180 degrees with the base 1, the pocket 5 is automatically opened or expanded thus loosening the papers so they may be easily removed or arranged. When the cover is closed its weight tends to close the pocket and clamp the papers.

Ithas been found from experience that this arrangement provides a good looking and a very desirable desk folder for keeping papers in order for constant reference and also that it will hold the papes in place without their falling out when the tile is handled or turned over on itsends.

From the foregoing description it will be seen that I have provided simple, inexpensive and efficient means for carrying out the ob. j ects of the inevntion, providing a handy and readily consultable file that is tidy and always in order. I

Having described my invention, what claim is:

1. In a folder, a base member, a cover overlying the base, an expansible hinge member uniting one edge of the cover and base whereby the cover and base may be separated to varying distances betweenthem, an expansible pocket secured to the base between the base and cover and adjacentone end thereof and extending transversely to the expansible hinge, and a non-expansible hinge uniting the pocket and cover adjacent the expansible hinge whereby'the expansible hinge member and the expansible pocket may expand or contract togetherto accomplish a variation in the distances between the base and cover.

2. In a folder, a base member, a cover overlying the base member, an expansible hinge member uniting one edge of the cover with oneedge of the base whereby the cover and base may be separated to varying distances between them, an expansible pocket extending from the hinged edge of the base to the opposite edge and secured to the base between the base and cover adjacent one end thereof,

and a non-expansible hinge member uniting the pocket and cover adjacent the expansible the base whereby the cover and base may be 1 separated to varying distances between them, and an expansible pocket extending from the hinged edge of the base to the opposite edge and secured to the base between the base and cover adjacent one end thereof whereby the expansible hinge member and the expansible a variation in the distances between the base and cover.

4:. In a folder, a base member, a cover, an expansible hinge member connecting one edge of the cover and base, an expansible pocket at one end of the base member extending from the expansible hinge member to the opposite edge of the base, and means uniting one edge of said pocket to said cover whereby the pocket will be expanded when the cover is opened.

5. In a folder, a base member, a cover member conforming with the base member, a flexible hinge uniting one edge of the base and cover, an expansible pocket member extending across one end of the base member and underlying the cover in a direction transverse to the flexible hinge member and means uniting one edge of the pocket to the cover whereby the alignment of the cover and base is maintained and the pocket will be expanded as the cover is opened and the cover and pocket will expand together.
